Definitions

  • the present invention relates to a system for conveying and selecting fruit and vegetable products.
  • systems of the type indicated above comprise a plurality of buckets, in each of which a fruit and vegetable product is accommodated, a conveying line of the aforesaid buckets, a member for determining certain features of the fruit and vegetable product, such as weight, size, colour, etc., a plurality of discharge and product packaging stations, and an assembly controlling the conveyance of products to the latter fruit and vegetable product stations according to the determined features.
  • the bucket is nothing more than a container presenting a bottom wall and four preferably outwards slanted side walls.
  • the assembly which controls the discharge of the fruit and vegetable product from the bucket comprises an actuator which controls the rotation of the bucket about a horizontal axis so that the fruit and vegetable product either drops and/or rolls out of its respective bucket.
  • the US-Patent 5,477,955 discloses a system for conveying and selecting fruit and vegetable products according to the preamble of claim 1.
  • FIG. 1 it is indicated by 1 a system for conveying and selecting fruit and vegetable products comprising:
  • the conveying line 3 is of the known type and in particular presents a mobile chain 8 along a loop route.
  • the conveying line 3 supports, according to a uniform distribution, a plurality of brackets 11 which support a respective plate 12.
  • each plate 12 is hinged to the respective bracket 11 so that it can turn about a horizontal pin 13 from a conveying position in which it is horizontal to a discharge position in which it is slanted by a predetermined angle.
  • the hinging pin 13 is arranged on the side of the line 3 facing stations 5.
  • Each plate 12 integrally supports a respective bucket 2.
  • the assembly 6 is of the known type and in particular shown in patent application BO2003A00280 by the same applicant.
  • the assembly 6 comprises a cam plate 14 installed by the side of the line 3 at each station 5 on the opposite side, a tappet profile 15 which extends downwards from a corresponding plate 12, and an actuator 16 arranged near each cam plate 14.
  • the actuator 16 comprises a horizontal stem 17 mobile between an extracted position in which it does not interact with the tappet profile 15 whereby the plate 12 and its tappet profile 15 remain in the conveying position and a retracted position in which, by means of a body 18, the stem 17 presses the tappet profile 15 against the cam plate 14 determining a rotation about the pin 13 of the plate 12 in contact between the tappet profile 15 and an upward ramp 21 defined on the cam plate 14. Now, such contact increases the rotation of the plate 12 and its bucket 2, favouring the release of the product from the bucket 2.
  • the cam plate 14 presents in sequence a downward ramp 22 which makes the plate 12 return to its horizontal conveying position.
  • station 5 comprises a conveyor belt 31 and respective handling means managed by unit 7 and not shown being of the known type.
  • the conveyor belt 31 presents, for its entire length, a plurality of appendixes 32 which define therebetween a plurality of seats 33 in which the fruit and vegetable product is discharged from the bucket 2.
  • bucket 2 is defined by a plurality of rollers 34 carried by two side fins 35 which extend upwards from plate 12.
  • the rollers 34 are parallel to axis X, are idly mounted and define an upward concave resting surface of the fruit and vegetable product.
  • each bucket 2 In use, one or more of the features of the fruit and vegetable product conveyed by each bucket 2 are determined by means 4; features such as weight, size, colour, etc.
  • unit 7 selects the station 5 where to discharge the fruit and vegetable product. Now, each passage of the bucket 2 at the selected station 5, the unit 7 activates the assembly 6 which controls the rotation of a predetermined angle (according to the dimensions in height of the cam plate 14) of the bucket 2.
  • the fruit and vegetable product from the bucket 2 slips essentially parallelly to itself into a seat 33 of the belt 31. Such slipping occurs smoothly by effect of the rotation of the rollers 34 impressed by the fruit and vegetable product itself.
  • the unit 7 may carry out different operating modes.
  • a first mode may envisage discharge into a seat 33 of only the fruit and vegetable products presenting a predetermined grade (or colour, or size) to reach a certain total weight or number of products.
  • a second mode may envisage discharge into a seat 33 of the fruit and vegetable products also of different grade (or colour, or size) to reach a determined total weight or number of products. Once the total weight or selected number of products in the seat 33 is reached, the latter is advanced to a packaging member of the known type and for this reason not shown, thus taking a new seat 33 at the line 3.
  • the bucket 2 may envisage only a reduced portion defined by the rollers 34. Furthermore, at least one roller 34 may be driven and therefore help the slipping of the product towards the belt 31.
